Lithium battery packs have strict requirements for the charger. If the charger is used does not meet the requirements, the lithium battery is pulled, and there is a safety accident. Lithium battery pack is no memory effect, the drum bag is caused by a factor? How to safely handle the battery drum, listen to Xiaobian 娓 娓.
How to safely process after lithium battery drum? 1. When half of the power is used, it starts to replenish the amount, and only complete discharge and complete charging maintenance will be performed in a very small number of cases (for example, for a few months to six months, it will be completely charged, frequently charged and discharge easy to crystallize. This can greatly reduce the amount of crystallin, which can significantly reduce drum phenomenon;.
Try not to rely on some methods to teach online, continue to use the battery. 3, lithium battery packs generally need to be professional recycling, if there is no way to deal with, throw it to the classification of telecommunications service providers service points to recover trash can. 4, usually, when charging, pay attention to the selection of the charger, for example, the rated charging voltage of the battery is 3.
7V, the limit voltage is 4.2V, try to exceed this voltage, can keep constant currents. Why does the lithium battery drum? one.
Excessive charging caused by overcharge can result in all the lithium atoms in the positive electrode material to the negative electrode material, causing the positive polarized grid to collapse, this is also a major cause of lithium battery pack charges decline. During this process, the lithium ions of the negative electrode are increasing, and the over-accumulation allows the lithium atom to be crystallized, so that the battery is bulging. two.
The overlapping drum SEI film will protect the negative electrode material, so that the material structure is not easy to collapse, and the cycle life of the electrode material can be increased. The SEI film is not a constant, there will be a little change in the charging and discharge process, mainly some of the organic matter will reversibly change. After the battery is excessively discharged, the SEI film occurs reversible to break the ring, protects the negative electrode material after the SEI destruction of the negative electrode material, thereby forming a lithium battery drum phenomenon.
If the charger is used does not meet the requirements, it will make the battery drum, and there is a safety accident, and even the explosion is possible. III. Problems of lithium battery pack manufacturing levels, electrode coating is uneven, and the production process is relatively rough.
These three factors have led to the use of the lithium battery pack during use, and the inside of the battery has occurred in a severe reaction of the short circuit, which generates a large amount of heat, causing electrolyte to decompose gasification, and the battery is drumping. Xiaobian warm remind everyone that the lithium battery drum is already a big problem, it is not recommended to use it. It may be the consequence of short circuit, fever, smoke, combustion, etc.
How does the lithium battery plant response to battery bulge? 1, must control the dehumidifier, control the moisture. 2, must control the production cycle and turnover time. Will the lithium battery drum will explode? Lithium battery packs may explode, be sure to stop using.
The lithium battery rises to overcharge when charging, the internal chemical characteristics of the battery changes, resulting in gas, generally polymer soft bag battery overcharge will "drum", if the steel shell battery will explode. Be careful when using, it is best not to use a cheap charger, the cheap charger has a large life of battery life. The battery of "drum" is best not to use, very dangerous, recommended replacement.
